Dinosaurs, Martians, and a belt-bending blast open Star Trek: Strange New Worlds S4

Star Trek: Strange New Worlds season 4 kicks off with a pulpy, time-warping mission: the Enterprise travels 65 million years into a Martian past where humans encounter dinosaurs and a Dol’Drm war on a fifth planet that sits where the asteroid belt should be. Cassell steals antimatter to wipe out the Dol’Drm, but the explosion reshapes Mars’ orbit and seeds the belt—an origin-story twist Spock ties to Olbers’ belt theory—raising existential questions about interfering with history. Pike ultimately chooses to let the Martians' assault proceed, suggesting humanity’s existence may hinge on this offbeat voyage. Dinosaurs, Martians and an origin-story twist make it a gleefully bold opener.

Prospector’s Rock Turns Out to Be a 17‑kg Meteorite From the Solar System’s Dawn

A metal-detecting prospector found a dense reddish rock in Maryborough Regional Park in 2015 that resisted cutting with a saw, acid, drill, and even a sledgehammer. Identified in 2018 by geologists at the Melbourne Museum as a 17‑kilogram ordinary H5 chondrite meteorite dating to about 4.6 billion years ago, it formed at the dawn of the Solar System and likely came from the asteroid belt. Diamond cutting revealed tiny chondrules inside, confirming its extraterrestrial origin and making it rarer than gold.

The Vanishing Asteroid Belt: A Threat to Earth?

The asteroid belt between Mars and Jupiter is gradually disappearing due to collisions and gravitational ejections, losing about 0.0088% of its mass every million years, with implications for understanding Earth's impact history and the solar system's evolution.

Disappearance of the Solar System's Asteroid Belt and Its Impact on Earth

The asteroid belt between Mars and Jupiter is gradually losing material at a rate of about 0.0088% annually, primarily transforming into meteoritic dust or escaping as asteroids that can impact Earth, indicating a dynamic and shrinking structure that has influenced Earth's impact history and future risk assessments.

Study Reveals the Gradual Disappearance of Our Asteroid Belt

A new study reveals that the asteroid belt between Mars and Jupiter is gradually losing material at a rate that suggests it was once about twice as massive 3.5 billion years ago, impacting Earth's impact history and future asteroid risk.

The Vanishing Asteroid Belt

The asteroid belt between Mars and Jupiter is gradually losing material at a rate of about 0.0088% annually, primarily through collisions that produce meteoritic dust and fragments that sometimes cross Earth's orbit, indicating a dynamic and shrinking region that has influenced Earth's impact history and future impact risk.

New Quasi-Moon Discovered Near Earth, Possibly Hiding for Decades

Scientists discovered Arjuna 2025 PN7, a quasi-moon in Earth's orbit that has been there for over 60 years, highlighting the existence of quasi-satellites and mini-moons around Earth, which are often mistaken for alien probes but are natural asteroids in resonance with our planet.

NASA's Ceres Discoveries Suggest Past Habitability and Potential for Life

NASA's Dawn mission revealed that Ceres, the largest object in the Asteroid Belt, may have supported single-celled life 2.5 to 4 billion years ago due to a once-active subsurface water reservoir heated by radioactive decay, although it likely no longer has an internal ocean today.

Ceres: The Hidden Ocean of the Asteroid Belt

Ceres, the largest object in the asteroid belt, is a nearly spherical dwarf planet with complex geology and evidence of a once-frozen ocean, making it a compelling target for future exploration and the search for past life in our solar system.

NASA’s Psyche Spacecraft Resumes Full Propulsion

NASA's Psyche spacecraft has resumed full propulsion after a temporary halt caused by a valve issue in its xenon propulsion system, which was successfully rerouted to a backup line. This recovery ensures the mission remains on track for its 2029 arrival at a metal-rich asteroid, with the spacecraft now operating reliably for its planned trajectory and scientific objectives.

Hidden Comet Discovered in Asteroid Belt: Are There More?

Scientists have discovered a new main-belt comet, 456P/PANSTARRS, in the asteroid belt between Mars and Jupiter, increasing the known count of such objects to 14. Main-belt comets, like 456P, exhibit comet-like activity such as outgassing and forming tails, despite having asteroid-like orbits. This discovery suggests that these comets could provide insights into the early solar system, challenging previous notions about the "snow line" where ice could exist during the solar system's formation.

Organic Material Found on Water-Rich Dwarf Planet Ceres

A new study using data from NASA's Dawn spacecraft has identified 11 regions on Ceres, a dwarf planet in the asteroid belt, suggesting the presence of an internal reservoir of organic materials. This discovery challenges previous theories that these materials were delivered by external impacts and instead supports the idea that they may have formed within Ceres. The findings, published in The Planetary Science Journal, highlight Ceres' potential astrobiological significance and its role in future space exploration.

New Main-Belt Comet Discovered by Planetary Scientists

Planetary scientists have confirmed the discovery of a new main-belt comet, 456P/PANSTARRS, located in the asteroid belt between Mars and Jupiter. This comet, identified by Henry Hsieh and colleagues, exhibits repeated activity due to ice vaporization, distinguishing it from asteroids that show activity from other causes. Main-belt comets are rare, and their study helps scientists understand the distribution of ice in the solar system.
